+* Relays public channel messages between mattermost, IRC, XMPP, Gitter and Slack. Pick and mix.
+* Supports multiple channels.
+* Matterbridge can also work with private groups on your mattermost.
+
+Look at [matterbridge.conf.sample] (https://github.com/42wim/matterbridge/blob/master/matterbridge.conf.sample) for documentation and an example.
+
+## Changelog
+Since v0.6.1 support for XMPP, Gitter and Slack is added. More details in [changelog.md] (https://github.com/42wim/matterbridge/blob/master/changelog.md)
+
+## Requirements:
+Accounts to one of the supported bridges
+* [Mattermost] (https://github.com/mattermost/platform/)
+* [IRC] (http://www.mirc.com/servers.html)
+* [XMPP] (https://jabber.org)
+* [Gitter] (https://gitter.im)
+* [Slack] (https://www.slack.com)
+
+## binaries
+Binaries can be found [here] (https://github.com/42wim/matterbridge/releases/)
+* For use with mattermost 3.3.0+ [v0.6.1](https://github.com/42wim/matterircd/releases/tag/v0.6.1)
+* For use with mattermost 3.0.0-3.2.0 [v0.5.0](https://github.com/42wim/matterircd/releases/tag/v0.5.0)
+
+
+## Docker
+Create your matterbridge.conf file locally eg in ```/tmp/matterbridge.conf```
+
+```
+docker run -ti -v /tmp/matterbridge.conf:/matterbridge.conf 42wim/matterbridge:0.6.1
+```
+
+## Compatibility
+### Mattermost 
+* Matterbridge v0.6.1 works with mattermost 3.3.0 and higher [3.3.0 release](https://github.com/mattermost/platform/releases/tag/v3.3.0)
+* Matterbridge v0.5.0 works with mattermost 3.0.0 - 3.2.0 [3.2.0 release](https://github.com/mattermost/platform/releases/tag/v3.2.0)
+
+
+#### Webhooks version
+* Configured incoming/outgoing [webhooks](https://www.mattermost.org/webhooks/) on your mattermost instance.
+
+#### Plus (API) version
+* A dedicated user(bot) on your mattermost instance.
+
+
+## building
+Go 1.6+ is required. Make sure you have [Go](https://golang.org/doc/install) properly installed, including setting up your [GOPATH] (https://golang.org/doc/code.html#GOPATH)
+
+```
+cd $GOPATH
+go get github.com/42wim/matterbridge
+```
+
+You should now have matterbridge binary in the bin directory:
+
+```
+$ ls bin/
+matterbridge
+```
+
+## running
+1) Copy the matterbridge.conf.sample to matterbridge.conf in the same directory as the matterbridge binary.  
+2) Edit matterbridge.conf with the settings for your environment. See below for more config information.  
+3) Now you can run matterbridge. 
+
+```
+Usage of ./matterbridge:
+  -conf string
+        config file (default "matterbridge.conf")
+  -debug
+        enable debug
+  -plus
+        running using API instead of webhooks (deprecated, set Plus flag in [general] config)
+  -version
+        show version
+```
+

+
+### mattermost
+#### webhooks version
+You'll have to configure the incoming and outgoing webhooks. 
+
+* incoming webhooks
+Go to "account settings" - integrations - "incoming webhooks".  
+Choose a channel at "Add a new incoming webhook", this will create a webhook URL right below.  
+This URL should be set in the matterbridge.conf in the [mattermost] section (see above)  
+
+* outgoing webhooks
+Go to "account settings" - integrations - "outgoing webhooks".  
+Choose a channel (the same as the one from incoming webhooks) and fill in the address and port of the server matterbridge will run on.  
+
+e.g. http://192.168.1.1:9999 (192.168.1.1:9999 is the BindAddress specified in [mattermost] section of matterbridge.conf)
+
+#### plus version
+You'll have to create a new dedicated user on your mattermost instance.
+Specify the login and password in [mattermost] section of matterbridge.conf
+
+## FAQ
+Please look at [matterbridge.conf.sample] (https://github.com/42wim/matterbridge/blob/master/matterbridge.conf.sample) for more information first. 
+### Mattermost doesn't show the IRC nicks
+If you're running the webhooks version, this can be fixed by either:
+* enabling "override usernames". See [mattermost documentation](http://docs.mattermost.com/developer/webhooks-incoming.html#enabling-incoming-webhooks)
+* setting ```PrefixMessagesWithNick``` to ```true``` in ```mattermost``` section of your matterbridge.conf.
+
+If you're running the plus version you'll need to:
+* setting ```PrefixMessagesWithNick``` to ```true``` in ```mattermost``` section of your matterbridge.conf.
+
+Also look at the ```RemoteNickFormat``` setting.

+# v0.8
+Release because of breaking mattermost API changes
+## New features
+* Supports mattermost v3.5.0
+
+# v0.7
+## Breaking config changes from 0.6 to 0.7
+Matterbridge now uses TOML configuration (https://github.com/toml-lang/toml)
+See matterbridge.toml.sample for an example
+
+## New features
+### General
+* Allow for bridging the same type of bridge, which means you can eg bridge between multiple mattermosts.
+* The bridge is now actually a gateway which has support multiple in and out bridges. (and supports multiple gateways).
+* Discord support added. See matterbridge.toml.sample for more information.
+* Samechannelgateway support added, easier configuration for 1:1 mapping of protocols with same channel names. #35
+* Support for override from environment variables. #50
+* Better debugging output.
+* discord: New protocol support added. (http://www.discordapp.com)
+* mattermost: Support attachments.
+* irc: Strip colors. #33
+* irc: Anti-flooding support. #40
+* irc: Forward channel notices.
+
+## Bugfix
+* irc: Split newlines. #37
+* irc: Only respond to nick related notices from nickserv.
+* irc: Ignore queries send to the bot.
+* irc: Ignore messages from ourself.
+* irc: Only output the "users on irc information" when asked with "!users".
+* irc: Actually wait until connection is complete before saying it is.
+* mattermost: Fix mattermost channel joins.
+* mattermost: Drop messages not from our team.
+* slack: Do not panic on non-existing channels.
+* general: Exit when a bridge fails to start.
+
 # v0.6.1
 ## New features
 * Slack support added.  See matterbridge.conf.sample for more information

+Package toml provides facilities for decoding and encoding TOML configuration

+MetaData type.
+
+The specification implemented: https://github.com/mojombo/toml
+
+The sub-command github.com/BurntSushi/toml/cmd/tomlv can be used to verify
+whether a file is a valid TOML document. It can also be used to print the
+type of each key in a TOML document.
+
+Testing
+
+There are two important types of tests used for this package. The first is
+contained inside '*_test.go' files and uses the standard Go unit testing
+framework. These tests are primarily devoted to holistically testing the
+decoder and encoder.
+
+The second type of testing is used to verify the implementation's adherence
+to the TOML specification. These tests have been factored into their own
+project: https://github.com/BurntSushi/toml-test
+
+The reason the tests are in a separate project is so that they can be used by
+any implementation of TOML. Namely, it is language agnostic.

+Package poly1305 implements Poly1305 one-time message authentication code as specified in http://cr.yp.to/mac/poly1305-20050329.pdf.
+
+Poly1305 is a fast, one-time authentication function. It is infeasible for an
+attacker to generate an authenticator for a message without the key. However, a
+key must only be used for a single message. Authenticating two different
+messages with the same key allows an attacker to forge authenticators for other
+messages with the same key.
+
+Poly1305 was originally coupled with AES in order to make Poly1305-AES. AES was
+used with a fixed key in order to generate one-time keys from an nonce.
+However, in this package AES isn't used and the one-time key is specified
+directly.

-// Package gcfg reads "INI-style" text-based configuration files with
-// "name=value" pairs grouped into sections (gcfg files).
-//
-// This package is still a work in progress; see the sections below for planned
-// changes.
-//
-// Syntax
-//
-// The syntax is based on that used by git config:
-// http://git-scm.com/docs/git-config#_syntax .
-// There are some (planned) differences compared to the git config format:
-//  - improve data portability:
-//    - must be encoded in UTF-8 (for now) and must not contain the 0 byte
-//    - include and "path" type is not supported
-//      (path type may be implementable as a user-defined type)
-//  - internationalization
-//    - section and variable names can contain unicode letters, unicode digits
-//      (as defined in http://golang.org/ref/spec#Characters ) and hyphens
-//      (U+002D), starting with a unicode letter
-//  - disallow potentially ambiguous or misleading definitions:
-//    - `[sec.sub]` format is not allowed (deprecated in gitconfig)
-//    - `[sec ""]` is not allowed
-//      - use `[sec]` for section name "sec" and empty subsection name
-//    - (planned) within a single file, definitions must be contiguous for each:
-//      - section: '[secA]' -> '[secB]' -> '[secA]' is an error
-//      - subsection: '[sec "A"]' -> '[sec "B"]' -> '[sec "A"]' is an error
-//      - multivalued variable: 'multi=a' -> 'other=x' -> 'multi=b' is an error
-//
-// Data structure
-//
-// The functions in this package read values into a user-defined struct.
-// Each section corresponds to a struct field in the config struct, and each
-// variable in a section corresponds to a data field in the section struct.
-// The mapping of each section or variable name to fields is done either based
-// on the "gcfg" struct tag or by matching the name of the section or variable,
-// ignoring case. In the latter case, hyphens '-' in section and variable names
-// correspond to underscores '_' in field names.
-// Fields must be exported; to use a section or variable name starting with a
-// letter that is neither upper- or lower-case, prefix the field name with 'X'.
-// (See https://code.google.com/p/go/issues/detail?id=5763#c4 .)
-//
-// For sections with subsections, the corresponding field in config must be a
-// map, rather than a struct, with string keys and pointer-to-struct values.
-// Values for subsection variables are stored in the map with the subsection
-// name used as the map key.
-// (Note that unlike section and variable names, subsection names are case
-// sensitive.)
-// When using a map, and there is a section with the same section name but
-// without a subsection name, its values are stored with the empty string used
-// as the key.
-//
-// The functions in this package panic if config is not a pointer to a struct,
-// or when a field is not of a suitable type (either a struct or a map with
-// string keys and pointer-to-struct values).
-//
-// Parsing of values
-//
-// The section structs in the config struct may contain single-valued or
-// multi-valued variables. Variables of unnamed slice type (that is, a type
-// starting with `[]`) are treated as multi-value; all others (including named
-// slice types) are treated as single-valued variables.
-//
-// Single-valued variables are handled based on the type as follows.
-// Unnamed pointer types (that is, types starting with `*`) are dereferenced,
-// and if necessary, a new instance is allocated.
-//
-// For types implementing the encoding.TextUnmarshaler interface, the
-// UnmarshalText method is used to set the value. Implementing this method is
-// the recommended way for parsing user-defined types.
-//
-// For fields of string kind, the value string is assigned to the field, after
-// unquoting and unescaping as needed.
-// For fields of bool kind, the field is set to true if the value is "true",
-// "yes", "on" or "1", and set to false if the value is "false", "no", "off" or
-// "0", ignoring case. In addition, single-valued bool fields can be specified
-// with a "blank" value (variable name without equals sign and value); in such
-// case the value is set to true.
-//
-// Predefined integer types [u]int(|8|16|32|64) and big.Int are parsed as
-// decimal or hexadecimal (if having '0x' prefix). (This is to prevent
-// unintuitively handling zero-padded numbers as octal.) Other types having
-// [u]int* as the underlying type, such as os.FileMode and uintptr allow
-// decimal, hexadecimal, or octal values.
-// Parsing mode for integer types can be overridden using the struct tag option
-// ",int=mode" where mode is a combination of the 'd', 'h', and 'o' characters
-// (each standing for decimal, hexadecimal, and octal, respectively.)
-//
-// All other types are parsed using fmt.Sscanf with the "%v" verb.
-//
-// For multi-valued variables, each individual value is parsed as above and
-// appended to the slice. If the first value is specified as a "blank" value
-// (variable name without equals sign and value), a new slice is allocated;
-// that is any values previously set in the slice will be ignored.
-//
-// The types subpackage for provides helpers for parsing "enum-like" and integer
-// types.
-//
-// TODO
-//
-// The following is a list of changes under consideration:
-//  - documentation
-//    - self-contained syntax documentation
-//    - more practical examples
-//    - move TODOs to issue tracker (eventually)
-//  - syntax
-//    - reconsider valid escape sequences
-//      (gitconfig doesn't support \r in value, \t in subsection name, etc.)
-//  - reading / parsing gcfg files
-//    - define internal representation structure
-//    - support multiple inputs (readers, strings, files)
-//    - support declaring encoding (?)
-//    - support varying fields sets for subsections (?)
-//  - writing gcfg files
-//  - error handling
-//    - make error context accessible programmatically?
-//    - limit input size?
